To block traffic based on BGP ASN, you need to use Cloud Armor network edge security policies. Backend security policies protect backend services (like those behind an external HTTP(S) Load Balancer), but for traffic directly to Compute Engine instances with public IPs, you need a network edge security policy. Firewall policies operate at the VPC level and do not have the capability to filter based on BGP ASN. The —network-src-asns parameter is specifically used with Cloud Armor network edge security policies to filter traffic based on the source ASN.

Exact Extract:

"Cloud Armor network edge security policies can protect external IP addresses of virtual machine (VM) instances and load balancers. They support rules that allow or deny traffic based on various criteria, including source autonomous system numbers (ASNs) using the --network-src-asns parameter."

"Network edge security policies are designed for traffic destined for external IP addresses of Google Cloud resources that are not behind an external HTTP(S) load balancer, such as Compute Engine instances with public IP addresses."Reference: Google Cloud Armor Documentation - Network edge security policies overview

Using Cloud Interconnect with Shared VPC You can use Shared VPC to share your VLAN attachment in a project with other VPC networks. Choosing Shared VPC is preferable if you need to create many projects and would like to prevent individual project owners from managing their connectivity back to your on-premises network. In this scenario, the host project contains a common Shared VPC network usable by VMs in service projects. Because VMs in the service projects use this network, Service Project Admins don't need to create other VLAN attachments or Cloud Routers in the service projects. In this scenario, you must create VLAN attachments and Cloud Routers for a Cloud Interconnect connection only in the Shared VPC host project. The combination of a VLAN attachment and its associated Cloud Router are unique to a given Shared VPC network.
